development of enantioselective phase-transfercatalysis for preparing important natural products or physiologically active compounds is quite attractive and challenging in terms of environmental consciousness. Although quaternary ammonium salts as phase-transfer catalysts are believed to require base additives for phase-transferreactions, we have discovered that even without any base additives, the enantioselective
